Crankcase (4 or 3 cylinders with cast iron bushing), clutch housing, oil pan, steering column, and so forth are all iconic examples of aluminum die castings. Automobile steering wheel structure, which was originally built of aluminum (in iron mold frame), is now predominantly injected with integrated magnesium to decrease weight and moment of inertia. Gearbox forks made of die-cast brass have a new market water body (copper cage rotor, antibacterial alloy parts in the medical industry). Compared with aluminum alloy, zinc alloy market is more varied, utilized for automobile industry, electronic products (hood, card fixing), luxury goods (perfume bottle cap, etc.), sports or medicinal. Finally, fishing, radiation protection, and counterbalance are all possible applications for lead alloy. Here, we are going to talk about background information about die casting.

a variety of machinery (cold chamber, hot chamber, etc.)
According to the changed alloy, cold chamber machine technology or hot chamber machine technology is applied. The two methods are distinct in the degree of holding furnace. Therefore, in the cold chamber molding, the liquid metal is pulled out by the automated ladle (or metering furnace), then poured into the metal container, and lastly injected by the horizontal injection piston. A vertical injection piston injects metal into the mold via a gooseneck and injection nozzle in hot chamber technology, which heats the injection system to 400 degrees Celsius. Zinc and lead alloys are the only metals eligible for this process (which are less corrosive than aluminum in terms of metal elements),
There is also the so-called "multi slider" hot chamber machine, which injects on the splitting surface. These machines (dynacast, techmire) have extremely high productivity and are specifically used for injecting very tiny components (tens of grams) of zinc, lead or magnesium alloys. Depending on the model, the machine contains two or four movable blocks on which the mold blocks are mounted. The technique is special, and the die is incompatible with the typical hot chamber die casting equipment.
Part quality control
The operator watching the machine does a complete visual inspection of the parts to look for any defects (recasting, faults, cracks). Internal faults that do not match component standards (mostly pores and shrinkage traces) are found by radiographic examination when parts are periodically removed from each team (the frequency is dependent on the criticality of the product). Air and water tightness may be evaluated manually or automatically after processing in certain circumstances, either by sampling or by checking the air and water tightness after processing. The leakin
